+## Adding a sidebar and a footer
+To enhance the usability of your wiki you can add a custom sidebar and a footer that are shown on every page. The sidebar will be displayed to the right of the main content and the footer below.
+
+To enable the sidebar, just add a filed named `_Sidebar.md` to your wiki. For a footer the file must be named `_Footer.md`.
+Both file types allow common markdown syntax to adjust the presentation to your needs.
+
+Very basic example for a sidebar:
+```markdown
+- [[Home]]
+
+### Content
+- [Page 1](Page-1)
+
+> knuts wiki
+```
+
+> To edit these special files in the Web UI you need to manually browse to the files, e.g. for our user *knut* and his *foobar* repo:   
+> `https://codeberg.org/knut/foobar/wiki/_Sidebar`
